These readings are not stored or logged as historical data
for future data collection. Instead, the readings taken at a
particular date/time in the interval remain available (or
persist) until they are overwritten by the readings taken at
the next consecutive date/time in the interval. For Modbus
applications, the scan rate also represents the rate at which
Modbus updates the data available to the RTU or the
Telog Ru-33. The RTU requests this data from either the
EMUX (Buffered Mode) or the monitor (Passthrough
Mode). The Telog unit requests this data directly from the
monitor. Please note that the EMU, when in use,
automatically retrieves the available (i.e., persisting) data
from the monitor every minute. When using the Telog Ru-
33, ADS recommends applying the same interval for both
the scan rate in the monitor and the rate at which the Telog
unit requests data from the monitor.
14. (applies only to Modbus/Telog Ru-33 applications) Select the
Enable checkbox (when applicable) and modify the following
parameters in the Modbus section as necessary:
ID Enter the slave address number from 2 to 57, 59 to 96,
or 98 to 247 to be used when facilitating communication
between the EMUX and RTU or the monitor and Telog
Ru-33. The numbers 1, 58, and 97 are used for other
addressing purposes and will not be recognized. Choose a
number that is unique from other slave IDs used by the
RTU or Telog unit when referencing other devices. For
Telog Ru-33 operations, ADS recommends considering
using 55 as the identifier through which to request data
from the monitor. The default ID is 1.
Delay Response Enter the amount of time, in
milliseconds, following a request before the monitor
returns the requested data to the RTU (through the EMUX)
or the Telog Ru-33. The maximum delay allowed is 2000
ms. The default delay response is 10 ms.
15. Select OK to create a LIF for the location in the database and
exit the dialog.
